Description

Sodium Acrylate is the sodium salt of acrylic acid, a key monomer and functional additive in polymer chemistry. Its primary value lies in its ability to introduce anionic carboxylate groups into polymer chains, imparting water-absorbing, thickening, and dispersing properties. This makes it an essential raw material for manufacturers in the superabsorbent polymer (SAP), water treatment, and personal care industries.

Application

• Superabsorbent Polymers (SAP): The primary application, used in the production of hygiene products like diapers, adult incontinence pads, and feminine care items.
• Water Treatment Chemicals: Acts as a co-monomer in scale inhibitors and dispersants for industrial cooling water and boiler water systems.
• Detergents & Cleaners: Functions as a builder and anti-redeposition agent in laundry and dishwashing detergents to enhance cleaning efficiency.
• Textile & Paper Processing: Used as a thickener, binder, and coating agent to improve product quality and processability.
• Adhesives & Sealants: Serves as a modifying monomer to improve adhesion, flexibility, and water resistance.
• Personal Care Products: Employed in formulations for creams, lotions, and gels as a stabilizer and viscosity modifier.
